Two violinists are trying to play in tune. however, whenever they play their a string at the same time they hear a beat frequency of 3.0 hz. one of the violinists measures with an electronic tuner and finds her a string is at 422 hz. what are the possible frequencies for the a string of the other violinist?

the possible frequencies for the A string of the other violinist is 419 Hz

Explanation:

given information:

= 3 Hz

the frequency of the first violinist = 422 Hz

to find the possible frequency of the other violinist, we use the following equation':

= l - l

3 = l 422 - l

= 422 - 3

= 419 HZ

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
